Apple Watch SE 3 (44 mm, GPS) / Samsung Galaxy Watch7 44 mm Bluetooth

A 40 mm version also exists with different size, display and battery values.

Because the LTPO panel can lower its refresh rate, the display keeps showing the time and notifications with the wrist down; this is the first SE with Always-On.

The 2000-nit peak helps readability in sunlight; using the always-on display shortens battery life.

Apple claims 4x better crack resistance than the SE 2.

The S10 enables the Always-On display, double tap and wrist flick gestures, on-device Siri and fast charging.

There is no ECG or blood oxygen sensor. The temperature sensor is not intended for medical use.

Feature availability varies by country.

Energy Score turns sleep, activity and heart data into a daily readiness score; AGEs Index is experimental and not for diagnosis.

Wrist flick dismisses notifications and calls, silences alarms and returns to the watch face with one hand.

This is single-frequency (L1) GPS; position can drift under trees and between tall buildings.

The L5 band helps separate signals reflected by tall buildings and trees; dual-frequency mode can increase battery use.

In Apple's test the watch stays connected to an iPhone over Bluetooth throughout; results vary with use and settings.

Times are with the included Apple Watch Magnetic Fast Charger to USB-C Cable; no adapter is included.

A fast wireless charging puck is in the box, but no wall adapter.

Availability of ECG and blood pressure depends on country and paired phone; blood pressure measurement is not offered in the US.

This version has no cellular connection; calls and notifications come through the paired phone.

5ATM describes water resistance suitable for surface swimming; it is not for diving or high-speed water sports.
